At least five people were killed on Sunday after two suicide bombers opened fire inside a church in southwestern Pakistan. Up to 18 people were wounded before the police managed to stop the attackers, officials said. The gunmen wearing explosives-filled vests stormed the church in Quetta city when Sunday services had just opened, exploding a suicide vest and shooting at the Christian worshippers, said Sarfraz Bugti, the home minister of Baluchistan province. Police guards at the church exchanged fire with the attackers before they could enter the main sanctuary, said provincial police chief Moazzam Jah. “There were nearly 400 people inside the church, but the attackers couldn’t get inside the services,” Jah said. “We killed one of them, and the other one exploded himself after police wounded him.” Local television showed ambulances and security patrols racing to the scene while women and children were being led out of the churchs main gate. Jah said the church had guards because Christian places of worship are often targeted by extremist groups. No one immediately claimed responsibility for the attack.
